Overview

The Würth Elektronik 14230224500 is a Triac and SCR Output Optocoupler from the WL-OCTR series. It features a PhotoTriac output without a zero-crossing circuit, operating in random phase mode. The device provides an isolation voltage of 3750 Vrms and supports a peak repetitive off-state voltage (VDRM) of 400 V. Key electrical parameters include a forward current (If) of 60 mA, a forward voltage (Vf) of 1.24 V, and a maximum trigger current of 10 mA. Power dissipation is rated at 330 mW. It operates within a temperature range of -40°C to +100°C and is housed in a SOP-4 surface-mount package.

Feature Summary

Random phase triac output capability for precise AC power control applications
High insulation voltage of 3750 Vrms ensuring robust safety isolation
Zero-crossing circuit omission allows for flexible firing angle control

Applications

AC motor speed control systems
Solid state relay implementations
General purpose AC power switching circuits

Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm RoHS compliance status as indicated in official documentation. Ensure storage conditions maintain integrity prior to assembly. Cross-reference datasheet revisions for any updates to mechanical dimensions or electrical limits before finalizing procurement orders.

Selection Notes

Select this component when random phase triggering is required rather than zero-crossing synchronization. The 400 V rating suits low-to-medium voltage AC loads. Verify that the 10 mA trigger current aligns with the driving circuit capabilities. Consider the SOP-4 package constraints for PCB layout and thermal management requirements during design integration.

Part Context

This part belongs to the WL-OCTR series of optocouplers designed for industrial and consumer electronics. It integrates an infrared LED emitter with a photosensitive triac detector. The series emphasizes compact packaging and reliable isolation performance for modern surface-mount assembly processes.
